The invention, which belongs to the technical field of aircraft overall design, particularly relates to a variable-configuration aircraft with foldable telescopic wings. The variable-configuration aircraft comprises an outer-section telescopic wing, a middle folding wing and an inner-section wing; the outer-section telescopic wing is connected with the middle folding wing through a sliding rail and a motion driving mechanism, so that the outer-section telescopic wing stretches out and draws back in a wing box of the middle folding wing. The middle folding wing is connected with the inner section wing through a rotating shaft and a rotating driving mechanism. Through wing folding and telescopic combined deformation, the wing span and the wing area can be greatly changed, so that the span-chord ratio is changed, the aerodynamic performance of different flight environments is improved, the flight envelope is expanded, and the use requirements of multiple tasks are met.
本发明属于飞机总体设计技术领域,具体涉及一种可折叠伸缩机翼的变构型飞机。包括外段伸缩机翼,中间折叠机翼、内段机翼,所述的外段伸缩机翼通过滑轨和运动驱动机构与中间折叠机翼连接,实现外段伸缩机翼在中间折叠机翼的翼盒内伸缩。中间折叠机翼通过转轴与旋转驱动机构与内段机翼连接。本发明通过机翼折叠、伸缩组合变形,能够极大地改变机翼展长和机翼面积,从而改变展弦比,提高不同飞行环境的气动性能,拓展飞行包线,满足多任务的使用需求。
